Magnes Meduza chalk block, Rockforce – climbing and gym chalk block (solid magnesium carbonate)

Magnes Meduza chalk block by Rockforce is a solid magnesium carbonate block formulated for climbers and gym users who need reliable hand dryness and improved grip. The compact block delivers consistent moisture absorption without loose dust, making it suitable for bouldering, sport climbing, training on campus boards and for use in gyms where powdered chalk is restricted. The product is intended for both indoor and outdoor sessions and offers a practical alternative to loose chalk or liquid formulas.

Advantages

The solid composition reduces airborne dust and prevents excess chalk spreading on holds and floors, while still delivering effective sweat absorption and friction enhancement. The block format is portable and long-lasting compared with single-use chalk pouches, and it can be used directly or rubbed into hands for controlled application. Compatible with training routines that require minimised chalk residue, the Magnes Meduza block provides stable performance across multiple climbs.

• Sport climbing and bouldering

How to use

Apply the Magnes Meduza chalk block by rubbing it across the palms and fingertips until the desired level of dryness is achieved.

Use sparingly during indoor gym sessions where chalk rules apply; test a small amount on holds if you are unsure about gym policies. For outdoor climbing, ensure hands are clean and dry before application to maximise adhesion. Replace the block when it becomes too small to handle safely.
